这个小型企业创新研究（SBIR）二期项目致力于开发和测试电磁阀系统（MVS），使其能够在无凸轮内燃机上实现电子控制可变正时。MVS是一种先进的致动器，用于进气和排气锥阀，用于控制内燃机中新鲜电荷和废气的流动。LaunchPoint技术公司将设计和制造MVS执行器，并在实验性内燃机上演示其操作。MVS技术的优势源于电磁弹簧执行器的特性，它在阀门开启和关闭过程中提供了对阀门位置和速度的有效控制。LaunchPoint吗?S的高性价比和强大的技术将使人们期待的电子控制可变气门正时在量产发动机上得以实现。这项研究的广泛影响是显著提高燃油效率，减少排放，改善传统火花点火和压缩点火发动机的功率特性。当一个可靠的电子控制系统交付时，这项技术的经济和社会影响将是广泛的。MVSactuator可以应用于汽车、卡车、推土机和固定式发电机的内燃机中。它将实现新兴的先进燃烧技术，如均质充电压缩点火和压缩空气混合燃烧。MVS执行器的广泛采用将导致石油使用量的大幅减少，对环境产生不利影响，如空气污染和温室气体排放，并提高能源独立性。

This Small Business Innovation Research (SBIR) Phase II project is dedicated todevelopment and testing of Magnetic Valve System (MVS) enabling implementation ofelectronically controlled variable timing on camless internal combustion engines. MVS is anadvanced actuator for intake and exhaust poppet valves utilized in internal combustion enginesfor control of flows of fresh charge and exhaust gases. LaunchPoint Technologies, Inc. willdesign and build the MVS actuator and demonstrate its operation on an experimental internalcombustion engine. The advantages of MVS technology originate from the nature of the magneticspring actuator that provides efficient control of the valve position and speed during valveopening and closing events. LaunchPoint?s cost-effective and robust technology will enableimplementation of highly anticipated electronically controlled variable valve timing on a massproduction engine.The broader impacts of this research are a combination of significant improvementsin fuel efficiency, reduction of emissions, and improved power characteristics of conventionalspark ignition and compression ignition engines. When a reliable, electronically controlledsystem is delivered, the economic and social impact of this technology will be broad. The MVSactuator can potentially be used in millions of internal combustion engines employed inautomobiles, trucks, bulldozers, and stationary generators. It will enable implementation ofemerging advanced combustion technologies such as Homogeneous Charge CompressionIgnition and Compressed Air Hybrid. Widespread adoption of MVS actuators would result insubstantial decrease of petroleum usage, adverse effects on the environment such as air pollutionand greenhouse gas production, and improve energy independence.
